Special flame-retardant and sound-isolation inner wall dry powder mortar for kitchen

Abstract

The invention relates to special flame-retardant and sound-isolation inner wall dry powder mortar for a kitchen. Good bonding force with a base surface is realized; materials are economical and practical; the cost can be saved; meanwhile, a base layer treated by the material cannot hollowly bulge; the construction site cleanness can be ensured; the environment-friendly requirements are better met; glass beads, building block recovery materials and magnesium aluminate spinel powder are added for achieving the effects of sound insulation and flame retarding; cattail fiber and sepiolite are mutually matched, so that the kitchen wall surface long-time cleaning effect can be achieved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a dry powder mortar for fire-retardant and sound-insulating inner walls specially used for kitchens. Background technique [0002] Existing building materials such as cement mortar are widely used due to their easy construction and high strength. However, with the improvement of user needs, the requirements for sound insulation performance of building materials are getting higher and higher. Sound insulation materials generally require high density and large thickness. At present, the density of composite building materials on the market is small, and the sound insulation effect is not obvious after the construction is completed. In order to achieve the purpose of sound insulation, it is often achieved by adding sound insulation cotton or sound insulation layer to the wall of the building, which is expensive and increases the difficulty of construction. .

[0003] The kitchen is an important place for every family and catering institution, but cooking in the kitchen will produce a lot of oil fumes, and at the same time, due to the use of various household appliances such as range hoods, it will also generate a lot of noise; and the kitchen, especially the kitchen of the catering institution, is fireproof It has always been the main point of attention in decoration, so it is necessary to develop a dry powder mortar for interior walls with functions of oil fume removal, sound insulation and flame retardancy
